Students, hobbyists, and fine artists enjoy the smooth, subtle gradations of Koi® Water Colors. These student-grade tube watercolors perform well when applied to wet or dry paper, allow for versatility in correction and layering, and give the artist the ability to create washes with soft edges and dynamic color possibilities. Koi's smooth and vibrantly pigmented colors instantly respond to water, are quick-drying, and contain a special binding agent for even pigment suspension that allows the painter to blend, spread evenly, create washes with soft edges, and layer colors.
